Rescue workers combed through muck and rubble today left by a devastating weekend mudslide in Washington state that killed at least 14 people and left scores more missing, and authorities said they expected the death toll to rise through the day.

Even as hopes dwindled of plucking anyone else out alive, about a dozen workers searched overnight for as many as 176 people reported missing since a rain-soaked hillside collapsed on Saturday, swallowing dozens of homes near Oso, Snohomish County Executive John Lovick said.

Compounding the sense of urgency was a fear of flooding as water levels rose behind a crude dam of mud and rubble that had been dumped into the North Fork of the Stillaguamish river by the slide in an area along State Route 530, about 90km northeast of Seattle in the Pacific Northwest state.

With no change overnight in the number of people missing, local fire chief Travis Hots said he expected the fatality count to rise throughout the day.

“The operational plan for the day is going to be challenging. The weather’s changed and we’ve got some rain coming in. That’s going to make it even more challenging for our folks that are on the ground there,” Mr Hots told reporters.

The disaster ranks as one of the deadliest US landslides in recent years, since 10 people died when falling earth engulfed homes in the coastal community of La Conchita, California in 2005.

Authorities said they were hoping the number of people listed as missing would decline as some may have been double-counted or were slow to alert family and officials of their whereabouts. Eight people were injured.

“I believe in miracles and I believe people can survive these events,” John Pennington, Snohomish County’s director of emergency management, told reporters.

But after three days, the operation was shifting from a rescue operation to a recovery mission, officials said.

Rescuers failed to locate any more people in the rubble by early today. Mr Hots said authorities were also turning back many volunteers due to unstable ground conditions and fears of another landslide that could sweep away people searching the mud and debris.

More than 100 properties were hit by the mudslide.

“The last thing that we want to have happen is people showing up in their cars and sneaking up on the pile, and they’re up there working independently on their own,” he said.

Search crews and volunteers were “dealing with devastation” on the ground, said Mr Pennington, the emergency management director, noting they cannot use heavy equipment because of the conditions and must work by hand.

President Barack Obama, who was in Europe for a meeting with world leaders, signed an emergency declaration ordering US government assistance to supplement state and local relief efforts, the White House said.

Speaking in The Hague, where he was attending a summit, Mr Obama began a news conference by addressing the disaster in Washington state and asking Americans to “send their thoughts and prayers” to those affected by the disaster.

“We hope for the best, but we recognise this is a tough situation,” he said.

The president also called Washington governor Jay Inslee to discuss the mudslide, Mr Inslee’s office said.

House Democratic leader Nancy Pelosi said on Twitter: “Grateful for first responders who continue search & rescue efforts.”

Meanwhile, a 22-week-old baby hurt in the slide remained in critical condition at Harborview Medical Center in Seattle after being taken there by helicopter along with his mother, who also was hurt, the hospital said.

The landslide was not the first to hit an inhabited area in Washington state. More than 100 houses were destroyed by a slow-moving landslide in the town of Kelso in the late 1990s.

But that was in a different part of the state. A report filed to the US Army Corps of Engineers in 1999 highlighted “the potential for a large catastrophic failure,” and was one of many warnings issued about the area where this weekend’s disaster occurred, the Seattle Times reported.

In looking for what might have led to the mudslide, authorities have identified a 1.1 magnitude earthquake that occurred in the area on March 10th, but it remains unclear if that definitely played a role in the disaster, Mr Pennington said.

A total of 156 workers were taking part in search and recovery efforts today and 50 National Guard members were expected to join later in the day.

Quicksand-like conditions forced rescue workers to suspend their efforts at dusk on Sunday.

Some workers, mired in mud up to their armpits, had to be dragged to safety. Search crew workers were forced again to retreat briefly on Monday from the western edge of the slide area after movement was detected along a 450-metre stretch of earth.
